I was on my way to the Kazasker İvaz Efendi Cami (which turned out to be closed for restoration, as was about a third of the mosques I tried to visit in 2015) when I passed this small masjid. I think the stone with some Arabic writing was about the only thing old, but having taken the pictures (and spent some time cooling off after a heavy climb uphill in the lovely breeze in the masjid) I show them anyhow.

There is a mosque dedicated to the same person, His Excellency Seyyid Emir Ahmet Buhari who was an eminent Islamic scholar and a descendant of Muhammad, but it is some distance from here and doesn't look inviting. I also found that he lived in the late 15th and early 16th century, came from the city of Bukhara in today’s Uzbekistan, introduced a dervish sect with roots in the spiritual side of Islam and that the sultan had a lodge built to house the increasing numbers of followers. Burial places of leaders of the sect are next to it. Some of these you see on one picture. There was a wooden building nearby, that probably was the lodge.
